Answer:
9/20
Step-by-step explanation:
In this scenario, there are a total of 55+33+12=100 possible outcomes. Out of these, 55 are salamanders, and conversely 45 are not. Therefore, the probability that she does not select a salamander is 45/100=9/20. Hope this helps!
D) 82 units
ΔBCD ≅ ΔEFG
In congruent triangles, corresponding parts are congruent
BD = EG
4x - 9 = 2x + 15
4x - 9 -2x = 15
2x - 9 = 15
2x = 15 +9
2x = 24
x = 24/2
x = 12
EG = 2x + 15 = 2*12 + 15
= 24 + 15
EG = 39 units
FE = CB = 17 units
Perimeter of ΔEFG = FE + EG + GF
= 17 + 39 + 26
= 82 units
